\n3.\tResource of power equipment and elaboration of lifespans.
\nScience manager – Dr. Sci., Prof. O. Chernousenko.<\/p>\n
Doctor of Technical Sciences, prof. O. Chernousenko – head of the school at present.
\n\tSuch scientific research has been carried out
\n–\tIs elaborated the complex system of estimation of the residual resource and prolongation of the operation of steam turbines of high capacity, which allows extending the life of steam turbines with the capacity of 200 – 800 MW to 350 thousand h.
\n–\tSolved heat problem with the problem of boundary conditions of heat transfer (Solid Works Simulation) and the task of calculating the gas dynamics of the gas mixture with the subsequent calculation of the heat, stress-strain state of the metal of the power boiler (ANSYS Fluent and Solid Works Simulation).
\n–\tIs developed a methodical approach to the calculation of damages and the residual resource of high-temperature elements of power equipment due to local non-uniformity of temperatures, and proposals are made regarding ways of extending the life of such elements:<\/p>\n
1)\tDeveloped the method of estimating the residual resource from low cycle fatigue, static damage and multi-cycle fatigue due to torsional oscillations, taking into account constructive and repair and restoration changes of high-temperature elements of power equipment and experimental studies of metal rotor steel 25\u04251\u041c1\u0424\u0410 and casing steel 15\u04252\u041d\u041c\u0424\u0410.
\n2)\tDeveloped a system of dry slag removal with the use of ash as a man-made raw material for construction with the use of technology for the issuance of ash with high concentration in the stream of waste gases (patented).
\n3)\tDeveloped system for pumping dust between hoppers with a high concentration of flow has been developed, which allows to improve the stability of the pseudo-liquefaction process in aeration piles and to save fuel in emergency situations on the block.
\n4)\tDeveloped the system of automatic control of the furnace processes of boilers with the supply of high pressure concentrations of coal dust to the burner with the activation of the currents of the burners for optimal gas speed ratio.
\n–\tIs developed the method of mathematical modeling and experimental research of combustion processes in stabilizer burners;
\n1)\twas created a mathematical model of the gas-dynamic structure of the flow of gas flow in stabilizer burners.
\n2)\tThe data on the influence of regime and constructive factors – the coefficient of excess air, the width of the stabilizer, the coefficient of shading of the flow on the formation of the temperature field.
\n3)\tAre developed modular microfacial burner devices of the stabilizer type with the combined supply of combustion components.
\n4)\tWas carried out a complex of experimental and calculation researches of the working process in stabilizer burner devices and determination of their energy-and-energy indicators.
\n5)\tFormulated recommendations on the choice of structural parameters of burners with stable high-performance intensive microfacial combustion.<\/p>\n","protected":false},"excerpt":{"rendered":"
